Step-by-step explanation:
<h3>Isolate y on both equations then equate </h3>
- x²-3x+2y=-4
- 2y=-x²+3x-4
- y=-x²/2+3/2x-2
Now you can equate it with second one to get x

Answer:
the answer is c
Step-by-step explanation:
x and y have to be at least 12, so that's why the greater than sign was used
the amount of money had to be at most $230, so that's why the less than sign was used
they said x and y represent black and white respectively, so that means x is black and y is white, so it is 18x and 20y
Answer:
7
cm²
Step-by-step explanation:
First, find the area of the big circle with the formula A = r²
A = (3)²
A = 9
Now, we can find the areas of the smaller circles. Since they have the same radius, they are congruent (will have the same area)
A = r²
A = (1)²
A =
Now, we will subtract the areas of the smaller circles from the area of the big circle to find the area of the shaded region:
9 - - = 7
So, the area of the shaded region is 7 cm²
